ABSTRACT
The authors measured flow velocity of intracranial arteries to venrify the patency of the parent arteries and branches after clip placement during aneurysm surgery. Before the clinical study, experimental sonographic recording was done with a feline aorta. The patency was evaluated by recording the flow velocity and pulse waveform using intraoperative microvascular Doppler sonography. The results of the clinical study were summarized as follows: (1) The patency of the parent artery can be proved. (2) The complete clipping of aneurysmal sac can be confirmed. (3) Vasospasm or narrowing of the arterial caliber can be detected. (4) Severe arteriosclerosis may mimic decreased flow velocity. It is suggested that the use of intraoperative microvascular Doppler sonography is an atraumatic and reliable method of testing the optimal clipping of the aneurysm and patency of the parent artery.
